Slope-intercept form: y = mx + b
[m is the slope, b is the y-intercept or the y value when x = 0 ---> (0, y) or the point where the line crosses through the y-axis]
To find the slope, you use the slope formula:
And plug in the two points
(-6, 2) = (x₁ , y₁)
(1, 16) = (x₂ , y₂)
[two negatives cancel each other out and become positive]
m = 2 Now that you found m, plug it into the equation
y = mx + b
y = 2x + b To find b, plug in one of the points into the equation
(-6, 2)
y = 2x + b
2 = 2(-6) + b
2 = -12 + b Add 12 on both sides
14 = b
(1, 16)
y = 2x + b
16 = 2(1) + b Subtract 2 on both sides
14 = b
Now that you found b, plug it into the equation
y = 2x + 14
I don’t know if you can even read this but make your graph points, rather than 1,2,3,4 etc. Make them 1/4,2/4,3/4,4/4, and 1/2,2/2,3/2,4/3, etc.. at least until you can plot your points. Make the numbers into mixed fractions or improper fractions whatever they call it. Make it to where the top is bigger than the bottom by multiplying the whole number by the denominator.
